Released: November 12, 2025

Survey Now v2.3.15 introduces an enhancement to the File Upload API that allows developers and survey creators to control how many files respondents can upload. This release also includes minor enhancements and bug fixes.

This update adds a new maxFiles property to the File Upload question type. You can use this property to specify the maximum number of files a respondent can upload. By default, the limit is 1000 files. The maxFiles property takes effect only when allowMultiple is set to true.

{
  "elements": [
    {
      "type": "file",
      "title": "Please upload your files",
      "name": "files",
      "allowMultiple": true,
      "maxFiles": 5
    }
  ]
}
